The president of a certain university receives a salary that is four times the salary of one of the department heads. The total of the two salaries is $210,000. a) What is the salary of the department head? b) What is the salary of the president of the university

Let x be the salary of one of the department heads

So 3x is the salary of the president.

Then x + 3x = $210,000

4X = $210,000

x = $210,000/4 = $52,500

Therefore the salary of one of the department heads is $52,500

and the salary of the President is 3 ($52500) = $157,500
